Detailed explanation-1: -A logical inverter, sometimes called a NOT gate to differentiate it from other types of electronic inverter devices, has only one input. It reverses the logic state. If the input is 1, then the output is 0. If the input is 0, then the output is 1.
Detailed explanation-2: -Rule: NOT Gates A NOT gate is a logic gate with one binary input and one binary output. The function of a NOT gate is to invert a value so that the input value is not the output.
Detailed explanation-3: -NOT gate. The simplest gate is the NOT gate, also known as an inverter. It accepts a single input and outputs the opposite value.
Detailed explanation-4: -A simple 2-input logic NOT gate can be constructed using a RTL Resistor-transistor switches as shown below with the input connected directly to the transistor base. The transistor must be saturated “ON” for an inverted output “OFF” at Q.
Detailed explanation-5: -For the NOT gate there is only one input (hence one input column, A), which can only have two possible values (0 and 1), so there are only two rows. As there is only one output, Y, there is only one output column.
